My most recent bag is micro chipped but my SA couldn’t scan the date code (she tried with a hand scanner and a bigger scanner in the backroom). I feel bad that she spent like 15 minutes trying and may have even asked someone else to try so I told her I would check it the next time I am in store. The Kirigami I got at the same time had the actual date codes inside. I can’t remember if I read somewhere that there’s a software we can download to scan our items ourselves (?).
